Python code to demonstrate a method to compute the factorial digists sum, i.e. 100 factorial (100!).
This test exercise I’ve recieved when I was looking for a Trainee Python Developer position.
n = 100
fact = 1
for i in range(1, n+1):
fact = fact * i
# Convert number to string
text_fact = str(fact)
# Initialize empty list for every letter of factorial string
summ = []
for letter in text_fact:
summ.append(int(letter))
print(sum(summ))648
